<P>PROBLEM TO BE SOLVED: To provide a conical roller bearing increasing the number of rollers without lowering stiffness of a retainer, and besides suppressing increase in torque as much as possible. <P>SOLUTION: In this conical roller bearing 1 provided with an inner ring 2, an outer ring 3, two or more conical rollers 4 arranged rotatably between the inner ring 2 and the outer ring 3, and the retainer 5 retaining the conical rollers 4 at predetermined circumferential intervals, two or more projections 5f having circular arc cross sections, which are projected toward the inner diameter surface of the outer ring 3 and form a minute clearance between the outer diameter surface of the pole part of the retainer 5 and the inner diameter surface of the outer ring 3 are formed on the outer diameter surface of the pole part of the retainer 5 at predetermined circumferential intervals. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
